view of the machine with end portions of the work carrying member broken away; Fig. :2 is a front elevation of the machine with end port'ons of the work carrying member broken away; Fig. 3 is a central transverse vertical section through the frame of the machine and the work supporting bed, the reciprocating head in this view being shown in side elevation; Fig.l' is a vertical section through the head on line {t4 of Fig. 5; Fig. 5 is a section on line" 5--5 of Fig. t looking down; Fig. 6 is a detailed view of the pawl guard shifting lever.

Referringto the accompanying drawings, the entire mechanism is mounted upon a rectangular box-like stand 1 whichhas a ledge 2 along the front side thereof upon which the fixed support 8 for the work carrying bed is mounted. At the top thereof the stand 1 has fixed thereto a pairof guides & between which the sliding head which carries the stone is mounted and, at

the rear thereof, the stand 1 is provided for driving the mechanism.

Extending longitudinally along the top of the support 3 for the sliding bed there is an undercut guide rib 6 which is. slidably engaged by the base portion 7 a of the work supporting bed. Extending longitudinally along the bottom of the base portion 7 of the work supporting bed there is a rack 8 which is engaged by a pinion 9 fixed to a shaft 10 which extends transversely through the support 3, the support 3 being provided with a suitable slot 11 to receive the pinion 9. The work carrying portion 12 of the bed rests upon the top of the base portion 7 thereof and is provided with a projection 13 on its underside which extends into a wide longitudinal slot '14: in the base member 7. The projection 13 is provided with a transverse threaded opening which receives a screw 15 which extends through the outer side portion of the base 7 and has a reduced end portion 16 to which is fixed the inner end of the reduced portion 16'and the hub of the hand wheel 17 there is a thrust plate 18 which is fixed to the base portion 7 of the bed and serves to hold-the screw 15 against longitudinal movcmena The work W is supported at the top of the upper portion 12 of the bed and is held against lateral movement by means of ribs 19 extending along the edges of the portion 12.

By rotating the hand wheel 17 the upper work carrying portion 12 of the bed may be shifted laterally so that the work may be accurately adjusted with respect to the reciprocating stone. The bed may also be so adjusted that the outer edge portion of the reed frame will not be engaged by the stone on its forward stroke. This adjustment al permits reed frames of various widths to be properly positioned with respect to the reciprocating head.

The entire mechanism is operated by a motor 20 mounted upon the rear platform 5 through a worm 21 and worm gear 21 within a gear housing 22 mounted on the platform 5, Connected to the worm gear is a vertical shaft'23 which is journaled at its lower end in the casing 22 and adjacent its upper end in a bearing bracket 2% attached to the rear side of the supporting stand 1. At its upper end above the top surface of the stand 1 the shaft 23 carries a wheel 25 to which is eccentrically connected the rear end .of a connecting rod 26 which is connected by a vertical pivot at its forward end to the sliding head 27. The head 27 IS provided on opposite sides thereof with undercut horizontal guide ribs which engage with undercut horizontal grorwes in the guide members 4-. It will thus be seen that when the motor 20 is in operation-the head 27 will be constantly reciprocated.

During the reciprocation of the head the work supporting bed is shifted longitudinally in one directionor the other with a progressively acted upon. from one end to the other by the stone. The step by step movement is imparted to the work carrying bed by the movementof the head andrthe mechanism by means of which this movement is effected will now be described. The shaft 10 is extended inwardly into the supporting stand 1 and is journaled in bosses 30 and 31 which project inwardly from the front and rear walls ofthe stand, respectively. Between the bosses 30 and 31 beveled gears 32 and 33. are rotatably mounted on the shaftlO. At one side of the shaft. 10 and at rightangles thereto thereis mounted a. horizontal spindle 34- which has its inner end adjacent the shaft 10 and mid way between the gears 32 and 33. At its inner end the spindle 34 has loosely mounted thereon a beveled gear 35 which meshes with the two beveled gears 32 and 33 on the shaft 10. Immediately behind the gear 35 on the spindle 34 there is a ratchet wheel 36 which rotates to the hub of the ratchet wheel 36 is an upwardly extending arm 37 which has adja cent the upper end thereof a longitudinal so that the work is.

with the gear 35. Pivoted slot 38 which receives a pin 39 carried by a bracket 40 projecting trom the underside of the slide 27. The arm 37 has pivoted thereto a pawl 41 which is preferably spring pressed toward theratchet wheel 36 into engagement with the teeth thereof. The teeth of the ratchet wheel 36 a re so disposed that the pawl 4:1v will engage therewith during the rearward movement of the head 27 and the pawl 41 will ride over the teeth during the forward movement of the head, head 27 is I'QClPl'OCtttQd the ratchet wheel 36 will thus be given an intermittentrotary movement in one direction.

The intermittent movement of the bed eli ected through the ratchet wheel 36 and in order to vary the rate of n'iovement of the bed for different operations I have provided means for varying the amount of angular movement which is imparted to the ratchet wheel 36 upon each reciprocation of the head 27. To this end the segmental guard plate 43 is fixed to the spindle 3 1 at the rear of the ratchet wheel 36 and has its outer portion projecting slightly beyond the periphery of the ratchet wheel into the path of movement of the pawl 41. To the outer end of the spindle 34: outside the stand 1 there is'fiXed an adjustinglever 4.4 which lies adjacent the wall of the stand 1 and is provided withan arcuateslot to receivea bolt 46 projecting from the wall of the stand. and adapted to clamp the lever in various adjusted positions. By adjusting the lever 44 the segmental guard 13 may be adjusted to prevent engagement of the pawl 41 with the ratchet wheel 36 during any desired portion of its rearward 1novement thus the extent of angular movement: of the ratchet wheel 36 for each stroke of the head can be accurately adjusted.

To provide a driving connection between the intermittently actuated-rachet wheel 36 and the shaft 10 which is geared to. the heck a sliding clutch 1nember4-7 splined to the shaft 10 is interposed between the gears 32 and and is adapted to be moved into engagement with either of two clutchele ine-nts 48 and 49, one on the gear 32 and thevother on the gear 33, by means of a suitable shifting lever 50. By means of the clutch element 47 either of the gears or 33 may be clutched to the shaft 10 whereby the shaft 10 will be given an intermittent rotary movement corresponding to the intermittent rotary movement of the ratchet wheel 38 and in either direction depending upon which one of the gears 32 or 33 is engaged by the clutch element 47. After the bed has traveled far enough the 'work' to have moved its full. length beneath the head, the clutch 47 will be shifted to reverse direction of movement of the bed and by adjusting the guard member 43, the rate of longitudinal movement of the in one direction for.

As the j Ill) ill

(ill

which is engaged by messes work may be varied. Where some portions of the work are rougher than others, it may be desirable to operate repeatedly upon these portions. The reversing geai permits the dircction of movement of the work to be reversed at any time so that the operations may be repeated upon any desired portion of the work. In finishing the work it is often desirable to move the stone a few times across widely separated parts of the work and in order to provide for rapid shifting of the work the shaft lO'has been extended and provided with a squared end 51 adapted to be engaged by ahand crank so e that by shifting the clutch member a7 to neutral position the movement of the work bed may be controlled by hand.

The slide 27 has an upright front end portion 52 which projects above the body thereof and serves as a support for the movable portions of the head. The front portion 52 of the slide has a reentrant vertical channel 53 formed in the front face thereof which forms a chamber for certain of the movable parts of the head. At the front edges of the channel 53 there are vertical undercut guide ribs 54 and 55 which serve as guides for a slide 56 which has an undercut groove 57 formed to receive the'guide ribs 54 and 55. The slide 56 at the top tlIldlOOttOlh corners thereof has forwardly projecting lugs 58 and 59 and on its front face has outwardly inclined guide ribs 60 i and 61 which extend vertically and serve as guides for a vertically movable tool carrier support 62 which has an undercut groove 63 in its rear face to receive the guide ribs 60 and 61.

Secured to the top of the channel portion 53 at the front of the head is a cap 6% which is provided with a screw threaded opening a vertically disposed tubular screw 65 provided with a hand wheel 66 at its upper end. Slidably mounted in the channel 53 is a block 67 which has an upwardly projecting stem 68 slid-able in the tubular screw 65. Interposed between the block 67 and the lower end of the tubular screw 65, there is a coiled spring 69 encircling the stem 68. The spring 69 serves to ieldingly press the block 67 in a downward direction and the screw 65 serves to-adjiist the tension of the spring 69. The block 67 has a recess 76 at its lower end which is open to the bottom and to the front of the block. \Vithin this recess there is mounted a pawl 7 l which pivots about a horizontal 7 3 extends pin 72 The pawl 71 has ing upwardly above the pivot and an abutiiient 74- on the inner side thereof below the pivot which is adapted to engagewith the rear wall of the recess to limit the swinging movement of the pawl. A coiled spring 75 is interposed between the rear wall of the recess 7 O and the arm 73 and serves to yieldingly press the abutment 7 4: against the wall adjusted position thereon by of the recess 70 thereby holding the pawl 71 in substantially vertical position. The lower end of the pawl71 engages the upper end of a vertical pin 7 6 which is slidably mounted in the bottom member at the lower end of tliechannel 53. Beneath the bottom of the head the pin 76 has a flange 77 formed thereon which is normally held in engagement with the lower end of a housing inemloci-78 secured to the bottom of the head by means of a coil spring 7 in 76 and interjiiosed between the flange 77 and the bottom of the head. The lower end of the pin 76 is tapered and rests upon, a cam track 80 which has an upwardly inclined portion 81 which serves at one portion of the stroke of thehead to elevate the pin 76 and through the pin 76 to lift the movable portions of the head so as to lift the stone out of engagement with the work. The caiii track 80 is preferably adjustable longitudinally to. permit working stroke to that the slide 67 is normallysupported by the pin 76, the tension of the spring69 not being sinlicient to overbalanccthe spring 75 so that while the pin is traveling over the forward straight portion ofthe track 80, the

parts will be held in the positionshown in Fig. 4. \Vhen, however, the pin 76 engages with the inclined portion 81 of the trackway there will be an additional upward pressure upon the lower end of the pawl7l slightly in front of the pivot 72 which will cause the lower end of the pawl to swing forwardly compressing the spring 75. As the pawl 71 9 surrounding the the length of the be varied. It will be seen moves forwardly, it will engage with a.

tooth of a vertically cured upon the rear face of theslide 56 so that the slide 56 and parts carried thereby will be elevated with the pin 76. .At the upper end of the slide 56 there are a pair of upstanding arms 83 to which theforksof a forked lever 84 are pivotally connected. The forked lever 84. straddles the adjusting screw 65 and is pivoted to a bracket85 flXQd to the upper end of the front portion 52 of the slide by means of a horizontal pivot 86 which; passes through the lever 84 iinn'iedi ately at the rear of the forked portion thereof. A counterweight 87 is slidably mounted upon the rearwardly extending portion of the lever 84: and isadapted to be secured in means of a suitable set serew 88. The counterweight 87 may be adjusted to as nearly counterbalance the weight of the movable portions of the head as desired. The tool carrier; support 62 has lugs 90 projecting laterally from the side edges thereof adjacent the center ani interposed substantially midway between the outwardly projecting lugs 58 andslide 56. Coil springs 91 are interposed between the lugs 90 of the tool carrier support and the upper lugs 58 of the slide and coil disposed ratchet 82 sellzi 59 of the j springs 92 are interposed between the lugs and the lower lugs 59 of the slide The springs 91 and 92 provide a. yielding support for the tool carrier holder as and permit movements of the tool holder support indqncndently of the slide.

The tool carrier support 62 has a dowuwardly inclined forwardly projecting skirt portion 93 which has side flanges projecting up *ardly therefrom and forming betweenthem a channel -for receiving the tool holder. Pivoted on a horizontal cross pin 95 extending between the flanges 94- there is a. tool holder 96 which has an upwardly extending arm 97. above the pivot between which and the upper portion of the support 62 is interposed a compression spring 98 which exerts outward pressure on the arm 97. Below the pivot 95 the tool holder 96 has parallel spaced arms 99 which are normally held by the spring 98 in engagement with an abutnient 100 which extends across the lower end of the skirt 93. i g The stone 101 is held between a pair of clamp members 102 and 103 which are socured together by means of clamping screws 104, the clamp members 102 and 108 having edge flanges 105 and 106 engaging the. inner and outer sides of the arms 99 of the holder so that the tool is slidably mounted between I the arms 99. The upper flanges 105 are cut away toward the lower end portion thereof to provide shoulders 107. Secured to the arms 99 are screws 108 behind which the shoulders 107 of the clamp engage whereby the downward movementof the clamping members is limited. A rubber butter 109 is interposed between the stone clamping members and the tool holder 96 which serves to normally hold the stone carrying clamp in engagement with the screws 108.

As the head is reciprocated, the stone 101 is yieldingly held in engagement with-the work. Upon rearward movement of the head, the stone 101 is so supported that any obstruction or irregularity of the work will cause the stone to swing upwardly, the spring 98 permitting the holder96 to swing about its pivot. Upon outward movement of the head, the stone will be cushioned by the butter 109 and also by the coiled springs 91 and 92 through which the tool carrier support is yieldingly supported so that any obstruction engaged by the stone whichmight otherwise damage or break the stone will cause the stone to be shifted upwardly, first compressing the butter 109, then shifting the support 62 bodily. The pressure exerted by the stone upon the work may be very accurately regulated by adjusting the counterweight 87 which determines the weight i1nposed upon the stone. In the DOlHlZtl/OP- erat-ion' of the machine the stone will bear against the work with a pressure determined connected to the support may be varied.
